Abstract

La présente invention concerne un appareil et des procédés permettant de réguler la fourniture de pression à un utilisateur tel qu'un patient. Un générateur de débit génère un débit de sortie à un orifice de sortie pour la fourniture à un patient, au moins un capteur permettant de mesurer les propriétés du débit de gaz sortant du générateur de débit à travers l'orifice de sortie ou fourni au patient mesurant les propriétés du débit. Un dispositif de commande est connecté fonctionnellement au générateur de débit et connecté à un ou plusieurs capteurs et conçu pour fonctionner en fonction d'un mode de commande de pression, dans lequel le dispositif de commande commande le générateur de débit pour produire une pression sensiblement constante, ou d'un mode de commande de débit, dans lequel le dispositif de commande commande le générateur de débit pour produire un débit sensiblement constant. Le dispositif de commande fonctionne dans le mode de commande de débit lorsqu'un patient est susceptible d'être réveillé et dans le mode de commande de pression lorsque le patient est susceptible d'être endormi.
